As you probably know gateway 2.3 beta is in development and its only a matter of time before its official release. I have some questions if anyone would like to take a shot at answering them be my guest. Lets say I'm in the emunand version 8.1.. What can I and can not do? Example am I still able to play my retail physical chartiage games? I getting into emunand mode requires a format of the 3ds sd card. I know it is possible to backup the sd card and then store the files back onto it once in emunand mode. My question is how is this possible? Please explain thoroughly on a how to on backing up and restoring the sd card... (I don't mean the gateway micro sd I mean the big 3ds sd card) Im going to go over what I think is correct when getting 8.1 emunand, please tell me if I'm correct.. Ok so I back up the sd card (which ill learn to do when someone answers questions 2) once done I goto gateway settings and select format emunand. After format is complete (keep in mind I will be on gateway 2.3) I goto settings upon recognition that it says GW3DS V 4.5 I then proceed to update it to latest version which is 8.1 once update is complete I put the old sd card files back on... and tada version 8.1 emunand! This is how I currently believe is the proper what to update the emunand. ~Thanks for any replies it is all much appreciated!
